MacBook Pro RD External GPU

Hey guys !
New to this forum ! I'm planning on buying my first laptop next month ( MBP RD ) But i'm pretty concern on the graphics . the gt650m is a good card but i'm don't think it'll be able to support future gaming or high end softwares ( AUTOCAD , 3DS Max ) . I've heard of the MSI GUS II , but it's not out yet if i'm not mistaken .

My question is , will it be coming out out in the near future ? December perhaps ?
